Abstract: 1,239,182. Knitting machines. K. I. J. ROSEN. 5. Jan., 1970 [22 Jan., 1969], No. 461/70. Heading D1C. In a yarn feed to a knitting machine, yarn F from a bobbin 2 is wound tangentially under tension on to a storage drum 7 on which it is displaced axially by an element lying at an angle on the drum periphery or sliding thereon and which forms an irregular ball from which the yarn is withdrawn axially. As shown bobbin 2 is carried on a pin 3 on a carrier arm 1 mounted on a knitting machine frame and is fed through yarn guiding elements 4, 5, 6 and a disc brake 8 to the driven storing drum 7 mounted beneath arm 1. Drum 7 is formed by a circular end carrying a series of rods 7a. The rim 9b of a spoked wheel 9 fits on the outside of the drum 7 with the wheel inclined to the longitudinal axis of the drum and biassed by spring F', the spokes 9a extending between rods 7a. When yarn builds up on drum 7, it finally causes wheel 9 to pivot against spring F' and operates a microswitch to stop the motor driving the drum. When sufficient yarn has been used, wheel 9 pivots down again and switches the motor on. In modifications, drum 7 may be stationary and the yarn wound on by a rotatable arm. Drum 7 may be a closed polished cylinder or may be polygonal. A sliding element may engage longitudinal grooves in the outside of the drum. A photoelectric device may be used to control the drum being operated by light reflected from the drum surface.

Abstract: 1,250,380. Echo suppressors. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 26 Aug., 1969 [29 Aug., 1968], No. 42474/69. Heading H4R. In a loudspeaking telephone system signals in each path are applied via first signal channels including rectifiers DA 1  and DA 2  and delay circuits S 1  and S 2  to respective comparator circuits K 1  and K 2  in which they are compared with signals derived from the other path via respective second signal channels including rectifiers DB 1  and DB 2 ; the second signal channels having lower gain than the first signal channels. The outputs from the comparators are fed to respective " NAND " gates ND1 and ND2 each of whose other input is derived from the output of the other " NAND " gate. The NAND. gate outputs also control respective variable gain circuits R 1  and R 2  in the signal paths to prevent singing. With no signal inputs on either path no outputs are obtained from the comparators and the low inputs to the " NAND " gates providing high outputs at points P 3  and P 4  so that the regulating devices R 1  and R 2  are in the high attenuation condition. An audio signal on one channel causes the respective comparator to provide an output causing the respective " NAND " gate to switch to low output condition switching the regulator in that channel to assume a low attenuation condition, and the interconnection of the " NAND " gates to maintain a high attenuation condition in the other signal path. The delay circuits DA 1  and DA 2  provide a hangover period covering short interruptions in speech, and have short rise time and delayed decay characteristics. The control signal channels may be made frequency dependent by inserting filters in FR 1 , FR 2  and FK 1 , FK 2  to discriminate against frequencies at which cross talk from loudspeaker to microphone is strongest, so allowing an interrupting party to gain control of the circuit by raising his speech level only slightly auxilliary, damping devices DR 1  and DR 2  may be provided to be conducting during no signal conditions, with the main variable gain circuits at an intermediate gain condition, to be switched by the outputs of the " NAND " gates to completely cut the transmission on the inactive path when a signal is detected on the other path. This allows the main gain controlling circuits to have an intermediate gain to provide smoother opening of a channel from the rest condition while preventing acoustic feedback during operation.

Abstract: 1,251,143. Optical recognition of objects. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 6 Feb., 1969 [9 Feb., 1968], No. 6475/69. Heading H4D. [Also in Divisions G1 and G2] A method of recognizing an object or its position and orientation comprises exposing the object 2 to coherent radiation 1, imaging the radiation scattered from the object at a point in space recording the intensity distribution of the radiation at 6 (e.g. a photographic plate), exposing the object a second time to coherent radiation and comparing the stored intensity distribution with that of the radiation scattered from the object at the second exposure. The width of the cross-correlating function of the stored intensity distribution and the intensity distribution from the second exposure with respect to a displacement or rotation of the object 2 in space is predetermined within given limits by the number and properties of the waves irradiating the object so that the measuring sensitivity and the measuring range are determined. The comparison is made at a photosensitive detector 9 which is associated with an indicating device 10 which shows, for example, the degree of movement of object 2. The plate 6 may be replaced by a television camera having a television image store means whereby comparison is effected with an electric or optical correlator. Preferably the radiation-scattering part of the object has at least one preferred direction of scattering. The method is applicable to relocation of articles during processing, analyzing fatigue phenomena, and analyzing corrosion and sedimentation phenomena.

Abstract: 1,259,231. Calibrating fluid-flow meters. ROTRON Inc. March 18, 1970 [March 18, 1969], No. 13043/70. Heading G1N. [Also in Division Fl] A fluid-flow meter comprises a pipe 12 divided by a metal sheet 40 into a principal channel C and a calibration channel P, the former communicating with an offset chamber 22 housing a rotor cage 24 for rotation at a speed proportional to fluid-flow rate with pressure taps 50, 52 respectively upstream and downstream of the rotor and coupled to a pressure transducer 58, the latter including a flow adjusting plug 42 and pressure taps 60, 62 coupled to a pressure transducer 70. The meter is calibrated with a fluid of known density, pressure and flow-rate by adjustment of the plug 42 which varies the cross-section of the meter and thereby the flow-rate, which is indicated by an indicator 48 coupled magnetically or mechanically to the rotor. It is shown that the meter error is proportional to the ratio of the square roots of the pressure drops in the principal and calibration channels respectively. The pressure transducers 58, 70 include resistances, 72, 74 respectively, variable as pressure and connected in a bridge circuit with resistances 76, 78 the latter of which represents the meter error or deviation and may be adjusted to rebalance the bridge. Alternatively the bridge unbalance current is displayed at 80 as a function of meter deviation. In this way a measure of meter error is obtained whilst it is in use.

Abstract: 1,266,662. Hydraulic turbines. HOLLYMATIC CORP. June 29, 1970 [Nov.13, 1969], No.31399/70. Heading F1T. In a hydraulic turbine plant steam from a generator 30 passes via a valve C and pipe 33 to a first container 23 causing liquid, e.g. water, in the latter to be forced through pipe 24, valve A, hollow shaft 17, and the interior of rotor 13 to issue through tangential nozzles 14 and drive the rotor, The latter is enclosed within a casing 35 having inclined baffles 11 on its interior surface which direct the liquid thrown out from nozzles 14 towards a drain hole 12 in the bottom of the casing. The liquid passing through hole 12 flows under gravity via valve B and pipes 27, 37 to second and third containers 26, 36 respectively. When all the liquid has been forced out of container 23 valve A, B and C are simultaneously operated so that steam pressure is directed via pipe 41 to container 26 so as to force liquid through pipe 39 to drive the rotor 13 whilst the drain liquid is directed through pipes 38, 37 to containers 23, 36 respectively. When container 36 is empty the valves are again operated so that liquid under steam pressure is forced from container 36. Thus a continuous supply of liquid to drive rotor 13 is maintained. Power is taken-off from the rotor via gearing 20, 21 and shaft 22.

Abstract: 1314178 Clamps FIRTH CLEVELAND FASTENINGS Ltd 27 Oct 1970 [27 Oct 1969] 52614/69 Heading E2B [Also in Division F2] A pipe or hose connector comprises an outer first sleeve into which is force fitted a second sleeve, the external surface of which, in whole or in part, is tapered longitudinally, such that the second sleeve when in situ within the first sleeve contracts and grips a pipe or hose positioned within it. The connector can be used either as a separate unit for coupling pipes wherein one pipe is formed as a socket and the second pipe a spigot or alternatively the outer sleeve forms part of one of the pipes. The connector 10 is preferably manufactured in one part, the two sleeves 11, 16 joined by a frangible annulus neck 14 which is broken when the sleeve 16 is forced into the sleeve 11 during assembly. In Fig. 2, the sleeve 16 has an annular rib 21 which cooperates with an annular groove 22 in the sleeve 11. In Fig. 3 (not shown), the sleeve 16 has projections (25) which engage apertures (26) in the sleeve 11. In Fig. 5 (not shown) the connector (39) has two integral sleeves 11 of enlarged cross-sectional diameter at the ends thereof, each sleeve 11 being connected to one of the pipes (40), (41), which have the same diameters, inserted therein. In Figs. 6, 7 (not shown), the outer sleeve of connector 39 is cylindrical and two pipes (40), (41) having the same diameters are coupled together by two tapered sleeves each gripping one of the pipes. In Fig. 8, the sleeve 16 has an annular groove 43 which cooperates with an annular rib 43<SP>A</SP> in sleeve 11. A sleeve 44 is disposed between sleeve 16 and the pipe positioned within it and serves as an additional sealing means. In Fig. 9 (not shown), the connector is the same as that of Fig. 5 (not shown) but the central neck portion (42) is of curved form and is used for joining pipes (40), (41) which are disposed at right angles to each other. In Fig. 10 (not shown), a flexible tube (47) is connected to each of the pipes (45, 46) by any one of the connectors of Figs. 1 to 3. In Fig. 11 (not shown) the inner surface (50) of sleeve 11 is tapered to form a neck of minimum diameter (51) halfway of the length thereof and which enhances the sealing effect when assembled. In Fig. 12, the annulus 14 is interrupted by two diametrically opposed slots 60 thus requiring less force when assembling and a longitudinal notch 61 to allow contraction of sleeve 16. In Fig. 14, the sleeve 16 has a tapered surface 17' arranged between two cylindrical portions whose surfaces are 15' and 71 and is provided with a flange 72, the edge 73 of which, when the joint is assembled, forms a uniform surface with the surface 13 of sleeve 11, Fig. 16 (not shown).
